    Google shares its data center cooling best practice - water and hot aisle containment "hot huts"

    Google has an end user friendly explanation of its data center cooling.

    Our emphasis on cooling systems might come as a surprise, until you consider how warm a personal computer can become during use. Data centers, which house thousands of computers, need to stay within a specific operating temperature range. Even though we run our facilities hotter than a typical data center, we need cooling systems - both to prevent server breakdowns and to provide a reasonable working environment for technicians working on the data center floor.

    After servers, the second largest consumer of power in a data center is the cooling system. We needed a cooling system which minimized our overall energy consumption. For this reason, we designed our own cooling systems from the ground up.

    Google uses hot aisle containment (hot huts) creating a higher delta T  across the water cooling coils at the top of the hot huts.

    IBM has used water cooling in its supercomputers for years and even used the waste heat for heating homes.

    SuperMUC combines its hot-water cooling capability, which removes heat 4,000 times more efficiently than air, with 18,000 energy-efficient Intel Xeon processors. In addition to helping with scientific discovery, the integration of hot-water cooling and IBM application-oriented, dynamic systems management software, allows energy to be captured and reused to heat the buildings during the Winter on the sprawling Leibniz Supercomputing Centre Campus, for savings of one million Euros ($1.25 million USD) per year.

    Now for those of you who think Google should use its waste heat to heat homes, there is the problem that Google data centers are not close to residential or commercial businesses that can use the low grade heat.

    In some data centers there is a hard fast rule of keeping water out of the data center, but if you want to be the most efficient you need to break some rules.

      I like the way you explained the difficult topic with such details. This is something I have been exploring about for a long time and you really provided all details of this topic.

      As you’d imagine, I founds lots of sites discussing about this hot topic of conceiving a girl or a boy, but the problem was that most of the tips and methods recommended seemed to be not so effective.

    This data cooling system created by Google is very eco-friendly. It showed Google's corporate responsibility in promoting environmental sustainability. It's a great innovation and should be followed by other big companies.

    It’s a shame all that energy goes wasted for nothing. It would be nice if they give it some use. I bet they’re already thinking on what to do with it.

    This is a state-of-the-art cooling system designed by Google. It's amazing how this company continue to lead the way in the data center management industry, while also remaining eco-friendly in their operations. I have a hunch that they are using powerful data center infrastructure management software to optimize their DCIM operations.
